The Tauranga Blood Donor Centre will remain closed for at least another week as repairs to fix flood damage continue.

Last week SunLive reported the centre's closure after some minor flooding from a broken water filter connection.

It's the second time in 10 months the place has been flooded, with the neighbouring Jenny Craig suffering from the overflow too.

Clinical nurse leader Annemarie Pidwell says the fire service 'are just champions”, after they came in last week and squeegeed out the building.

She says water connection has been investigated and pressure tested, but no one's sure what's causing the flooding.

Recruiter Jodie Houltram says they're unsure when they'll be open again, although naturally they're hoping it's sooner, rather than later.

'We want to say mid next week, but that's just an estimate. It just takes a long time to dry out the walls, as well as the painting that has to happen.”

Around 200 appointments have had to be cancelled as a result of the closure, mostly with regular donors.

'I'm just trying to organise everyone and make sure our donors aren't coming in at the moment.”

In the meantime, work continues, with the painters kindly volunteering to work during the weekend to get the centre up and running as soon as possible.
